Upper surface reddish brown of varying shades, deeper in the 9- Thorax 

 with a dorsal ferruginous stripe, teguUe sometimes tinged with rosy. Abdomen 

 with a distinct dorsal and lateral dark line in the 9- laterally also marked with 

 bluish gray; in the % the dorsal line only is distinct. Primaries paler, some- 

 times whitish towards base, in well marked specimens crossed by two undulating 

 darker lines, which are, however, usually wanting. A very distinct brown, 

 transverse line from costa at basal third, to the hind margin near the hind angle ; 

 terminating on a somewhat purplisii dark patch, which runs for a variable dis- 

 tance along the inner margin. Beyond this line the wing is often powdered with 

 lilac or pale blue, most distinct outwardly ; a series of three or four dusky lines 

 with paler, powdery interspaces from costa at outer fourth, gradully losing them- 

 selves in the ground color before or at the middle of the wing; a large yellow 

 spot before the apex and a smaller, yellow, or whitish spot before the anal angle ; 

 a pale, bluish shade through the terminal space. The terminal space is often 

 darker and the interspaces opposite the cell often show dusky longitudinal shades. 

 From the ante-apical pale spot a rusty shade sometimes runs to the disc, nar- 

 uowing and losing itself in the ground color. Discal spot small, brown, often 

 wanting. Secondaries with disc yellow, ocellate spot black, the pupil blue; the 

 costal region is darker, brownish, with two paler lines crossing it before the apex. 

 Beneath, primaries paler at base than upper side, outwardly darker, the mark- 

 ings of upper side reproduced and much stronger. Secondaries dusky toward 

 base; three dark, somewhat irregular discal transverse lines with pale inter- 

 spaces. Outer margin irregularly rather dark brown, the space between the dark 

 margin and the discal lines is brighter, more ochre yellow, and is the lightest 

 part of the wing. Expands 2.25 — 2.50 inches ; 56 — 63 mm.

The corneous projection of the side piece of the S genitalia is 

 short, very Ijroad, sj)atu]ate and obtusely rounded. 



This is one of the rarest of the group, and does not seem widely 

 distributed. It is very close to myops in pattern of maculation, but 

 is much paler, the markings very much less distinct. It seems more 

 variable than the specimens seen by me would indicate, the variation 

 being in the shade of the lighter parts of the wing. Mr. Strecker's
